New User Registrations - Where is this managed?

Where is the new user auto email notification managed? I don't see it anywhere. I would like to add some custom text informing the new user to go to my signup page to log in when they return. Wordpress sends out a notification but the user logs into the WP login page to view profile. I don't want them to visit profile because there is no way to help them to get to the content from there.

So, what is the process to get the system, Member plugin, to send out new user registrations with custom text?

Thank you!
